IMPROVEMENT IN CHURNS.V

Specification forming part of Letters Patent No. 57.750, dated September 4, 1866.

To all whom it may concern:V Be it known that I, JAcoB H. MENDEN- HALL, of Cerro Gordo, in the county of Randolph and State of Indiana, have invented a new and useful Improvement in Churns and I do hereby declare that the followhig is a full,

clear, and exact description thereof, which will y enable others skilled in the art to make and use the same, reference being had to the accom'- panyin g drawings, forming part of this specification, in which- Figure lis a vertical section of my improved churn, taken through the linexx, Fig. 2. Fig. 2 is a horizontal section of the saine, taken through the line y y, Fig. l.

Similar letters of reference indicate like parts.

My invention has for its object to furnish an improved churn, easily and conveniently operated, and which will do its work quickly and thoroughly; and it consists, first, in the combination of the dasher shaft, gearwheels, crank-shaft, and crank or cranks with each other, and with the box and cover of the churn, when the said parts are constructed an d arranged as hereinafter more fully described; and second, in the combination ofthe gathering-board and spring-catch with the dashershaft, as hereinafter more fully described.

A is the boX of the churn, which is made nearly square or rectangular. The central parts of two opposite sides extend upward above the top of the churn, as shown at c and Zand have notches formed in their upper ends for the bearings of the crank-shaft B. The cover C is made in two parts, c and c2, the part c covering a little more than half the top of the churn. This part has a piece, c3, attached to ils upper surface, at the center of the top of the churn, in which is formed a third bearing for the crankshaft B. The part c of the cover lifts off with the crankshaft B, and may be secured to the box A of the churn by hooks or in any other convenient way. The part c2 of the cover C is slid into its place from the side of the churn.

rIo one or both ends of the crank-shaft B are attached cranks D, as shown in Fig. 1. To the crank-shaft B is adjustably attached a bevel gear-wheel E, the rim of which passes down through a slot in the part c of the cover C, and meshes into a bevel-gear wheel, F, adjustably attached to the dasher-shaft G.

rllhe gear-wheels E and F are secured to the shafts B and G by set-screws passing through the hubs of said wheels and screwing against the said shafts, so that they may be moved to compensate for their wear, and thus be always kept in proper workin g position.

The dasher-shaft G is pivoted to the bottom a3 of the box A, and to the cover C by pivoting-pins attached to the ends of the said shaft, and working in sockets formed in the centers of said bottom and cover, as shown in Fig. l. To the lower part of the shaft G are attached four wings or dasher-blades, H, the upper edges of which are notched or serrated, as shown in the drawings. These wings throw the milk into currents, which currents are broken up by the action of the strips I, attached to the sides of the box A for that purpose. and which vextend from the top of the churn down so far that they just clear the upper edges ofthe dasher-wings H as the dasher is revolved.

Jis the gathering-board, which is made with avertical hole through it, through which passes the dasher-shaft G, as shown in Fig. 2. The gathering-board J can be moved up and down along the shaft G, and is held in place in any desired position by the spring-catch K, one end of which is attached to the side of the board J, and the other end is bent over at right angles a-nd passes through a hole in the side ofthe board J, and into one or the other of the holes .formed in the side of the shaft G,

as shown in Fig. 1. lhis gathering-board need not be used unless desired, or when a large quantity of milk is to be churned, and its effect is to gather the butter quickly and thoroughly.

I claim as new and desire to secure by Letters Patentl. The combination of the dasher H, shaft G, adjustable gear-wheels E and F, crankshaft B, and crank or cranks D, with each other, and with the box A and cover C, when said parts are constructed and arranged substantially as herein described, and for the purposes set forth.

2. The combination of the gathering-board J and spring-catch K with the dasher-shaft G, substantially as herein described, and for the purposes set forth.

The above. specification of my invention signed by. me this 28th day of June, 1866.

JACOB H. MENDENHALL.
